Abstract: 1298616 Dynamo-electric machines ALLISCHALMERS MFG CO 6 May 1970 [13 May 1969] 21848/70 Heading H2A A rotary machine giving an output signal representing the vector sum of electrical input signals comprises a ferromagnetic stator having sets of angularly displaced first and second teeth, a first energizing winding having turns on one first tooth and a second energizing winding having turns on one second tooth, an output winding having turns on both the one first and the one second teeth, and a ferromagnetic rotor arranged so that the permeance of the flux paths between the teeth and rotor varies cyclically. The rotor may have a lobe 28, as shown, or may be circular and have regions of differing permeability, or may comprise skewed, segmented laminations. The embodiment shown comprises two sets of teeth 1, 3, 5 ... 11, and 2, 4, 6 ... 12, energizing windings on all of the teeth of each set being connected in series to a respective signal source 101 or 102. Each of the three output phase windings includes turns on teeth of both sets, e.g. phase A output winding includes part windings 81, 84, 87 and 90 respectively on teeth 1, 4, 7 and 10, the part windings on teeth of each set being connected subtractively. The rotor is driven by a motor 34 so that the output is modulated at a frequency dependent on motor speed, has an amplitude dependent on the amplitudes of energizing signals V c  and V s , and a phase dependent on the relative magnitudes of V c  and V s . The output may be used, as shown, to control a motor control circuit 35, e.g. a cycloconverter, energizing the windings of motor 34. The machine may form part of a circuit for controlling the speed and torque of a synchronous motor (Fig. 7) as in Specification 1,198,980. The first and second teeth may be formed on separate stators 150, 153, Fig. 15 (not shown), and co-operate with different rotors (125, 125<SP>1</SP>). Alternatively, the teeth of one set are bunched together at one part of the stator circumference and the teeth of the other set are bunched together substantially diametrically opposite the first set to reduce interference between the fluxes of the two energizing windings. The energizing windings may be A.C. excited as shown, or D.C. excited, Fig. 14 (not shown). The rotor may be inside or outside the stator.

Title: Improvements in and relating to milking machines
IPC: A01J5/10
Filed: 1952-09-01
Abstract: 713,395. Cow-milkers. SABROE, V. P. N. Sept. 1, 1952 [Aug. 30, 1951], No. 21965/52. Class 84 A milking machine of the kind working with intermittent suction on the teats of the cow in leat-cups, the pail of the milking machine being connected to the teat-cups by means of a tube which is alternately connected to and disconnected from the vacuum in the pail by means of an apparatus mounted on the lid of the pail, is characterized in that said apparatus consists of a pulsator mounted directly on the lid of the pail, the pulsator being of the kind comprising two diaphragms and an intermediate piston, of. which the one diaphragm is operated by the pressure of the atmosphere and the other by the pressure in a space in the pulsator connected with the tube to the teat-cups, and by the flow of milk through this tube to the space, so that the working speed of the pulsator is regulated also by the quantity of milk flowing through the pulsator. Two such pulsators may be provided each dealing with two of the four teats. The pulsator is mounted directly on to the lid 30 of the milk pail and comprises two parts 4, 5 sealed together by the packing 16. The upper diaphragm 1 is fastened to a piston 2 the bottom end of which rests against a diaphragm 3. The bottom of this diaphragm is in connection with the atmosphere. When a vacuum is applied to the pail, air is sucked through the pipe 12, opening 8, holes 20, spaces 17 and bores 11 and 27. When the pressure above diaphragm 1 has fallen sufficiently, it is forced upwards by the pressure on diaphragm 3 and remains there until air has bled into the space above it through a leak 9. The diaphragms then fall and the process restarts. The presence of milk above the diaphragm 1 aids its downward motion. The milk flows through the parts 20, 17, 11 and 27 into the pail.

Abstract: 1,098,615 X-ray apparatus.. M. C. HARRISON May 25, 1965 No. 22026/65 Heading H5R [Also in division G5]. Apparatus, for use in training radiographers, includes a prism 10 of material transparent to light and X-rays, and in which a number of different objects, some of material opaque to light and X-rays, are embedded. The prism is mounted on the top of a viewing box 32 in required position which can be noted by means of a grid graticule 30 marked on a sheet of plastic 29. An X-ray tube is supported on the box by a tripod 26 whose position is also noted. A film-holder can be positioned on the top of the box 32 underneath the sheet 29 and a radiograph of the prism taken. After development, the exposed film is replaced in the position occupied by the film-holder, the prism replaced in an identical position and the film (radiograph) viewed from the position previously occupied by the X-ray source (i.e. the centre of the tripod ring 27). The shadow images produced by the objects in the prism can thus be compared directly with the actual objects corresponding to them. Other radiographs may be taken with the prism in different positions or with X-ray incident on the prism from different angles. The prism material may be a plastic of the acrylic resin type, a methyl metracrylate monomer. The objects embedded in the block (Fig. 2, not shown), can consist of simple geometrical shapes made out of lead, e.g. a thin rod (11), an L-shape (13), a ladderlike object (15) or a metal sphere (16). Depending on the positioning of the apparatus, the shadow images produced by these vary in the amount of distortion of the original object shape. Other objects opaque or semi-opaque to light but transparent to X-rays, e.g. plastic coloured spheres (17A, 17B, 17C) (simulating gallstones) or air bubbles (18) demonstrate that such objects do not show on the radiograph.
